Abstract

The invention provides a gemel elastic device which comprises a headstock, an arm piece, a connection shaft and an elastic piece; the headstock is provided with a holding chamber; the arm piece is provided with a convex wheel part which is positioned at one side of the chamber and is pivoted with a connection shaft, wherein, the spring piece is a U-shaped piece which is provided with one end and another end which are connected and arranged at intervals and opposite to each other, one end is a fixed end, and the other end is a force-application end; the fixed part is stuck to the bottom of the chamber of headstock, and an opening slot is arranged at the part of the convex wheel part being next to the arm piece; in the virtue of the application part of the spring piece going through the opening groove, the convex part is withstood.

Description

technical field [0001] The invention relates to a hinge elastic device, in particular to a hinge elastic device which utilizes a U-shaped spring piece arranged in a chamber of a hinge head seat to provide elastic force for the pivotal positioning of the hinge. Background technique [0002] General furniture hinges are often used for cabinet hinges. The basic structure includes a head seat, an extension arm and a fixed seat. The extension arm is pivotally connected to the head seat and can be expanded. It is connected to the fixing seat fixed on the cabinet, and the elastic part is arranged in the head seat to exert force on the extension arm, and has a closing force when the door panel is pulled back to cover the cabinet. [0003] The hinge design of this kind of furniture and cabinets, as far as the type of "elastic part" provided in the head seat is concerned, most of them adopt the type of torsion spring, such as U.S. Patent No. 5,604,956, No. 5,617,612, No. 6,393,663 B1,...
